I found something about wine that I didn’t know

That's right.

For red wine, the skin of the (dark) grapes are left in after the grapes are crushed, and filtered out later.

For rosé wine, the skin stays in for a shorter period.

For white wine, the grapes can be dark or green, it doesn't matter - the liquid is filtered right away, so it doesn't acquire the colour of the skins.

Then there is orange wine, which is made from pressing white grapes and leaving the skin in with the liquid. This is a process that was never practiced in the big wine-producing nations of Western Europe but was popular in Eastern Europe, and is now spreading worldwide.
